Everyone would like to point out the Xbox 360 version is getting isolated from the others, basically. That are justified and correct. But in your situation, there's a chance it'd be better than the other option. Can you give the specifications on the laptop? In general a laptop probably can't do it, unless it's specified as a gaming laptop from the start.
If you do get it for Xbox 360, we can play together.
By the way, does anyone think the Roll Cage Skin is the coolest pre-order exclusive? I'd say so in the idea it's the biggest difference from the original. The other two skins are a change in their colors and a little flag on their extended antenna. The Roll Cage is more of a model addition than a simple skin modification.
